METAL WINDOW FRAME AND SASH.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed February 23, 1916. Serial No. 79,818.

To all whom it may concern Be it known that I, HARRY E. CAMPBELL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Metal Window Frames and Sashes, of which the following is a specification.

The invention relates to metal windowframes and sashes, and consists in the construction, hereinafter described, whereby the sash rails are received and concealed in the tubular jambs, so that the frame opening is unobstructed over its entire width, and the lighting space of the window increased.

In the accompanying drawingsFigure 1 is a vertical section of my window-frame and sash on the line at, m of Fig. 2. Fig. 2 is a section on the line y, y of Fig. 1. Fig. 3 is an enlarged section of a portion of Fig. 2, sllioowing the sash rail entering the tubular 3am Similar numbers and letters of reference indicate like parts.

The window-frame, as here shown, has a lintel A, sill B and two tubular jambs, here rectangular in cross section. Sashes D, E slide in said frame, and are provided with suspension chains F passing over pulleys disposed within the lintel and carrying sash counter-weights G, which move up and down in compartments formed by the dividing partition H in the jambs. In the inner wall I of each j amb are formed two vertical openings J, K. The glass pane 1 enters the openings J, K and extends into the tubular jambs, so that the side rails of the sash which support said pane are concealed within said jambs. Each sash enters corresponding openings in the inner walls of the opposite jambs, so that a description of one sash in its relation to one opening in the jamb wall at one side applies to both sides of both sashes.

The glass pane 1 is placed in a metal frame, the side rails of which are preferably formed of two plates 2, 3-plate 2 being flat, and plate 3 being bent twice at right angles to form a pocket receiving the vertical edge of said pane. The plates 2 and 3 beyond the pocket are connected by a headed screw bolt 4 passing through a slot 5 in a laterally-extending plate 6 which makes sliding contact with the outer wall 7 of the jamb. The plates 2, 3, may, if desired, make sliding contact with the vertical edges of the wall I, and so act as wearing plates. The main object, however, is to get the side rails of the sashes out of sight, so that from jamb to jamb a clear sheet of glass shall appear. Not only is a greater amount of light space within the frame thus secured, but the joints between the vertical edges of the sashes and the side rails are completely protected from the weather, so that putty or packing material at said joints is unnecessary, nor is any other weather tight construction at these joints required, thereby cheapening and facilitating the construction.

I claim:

1. A metal window-frame, comprising two hollow jambs, each having a vertical opening through its inner Wall, and a sash hav ing a glass pane and supporting side rails therefor: the said side rails and the edges of the pane supported thereby entering said jambs through said wall openings so that said side rails are concealed in said jambs, whereby the light space between the inner walls of the opposite jambs is rendered unobstructed by said side rails.

2. A metal window-frame, comprising two hollow jambs, each having a vertical opening through its inner wall, a glass pane slidable in said frame and entering said jambs through said openings, and, within said jambs, means secured to the vertical edges of said pane for reinforcing said edges.

3. A metal window-frame, comprising two hollow jambs, each having a vertical opening through its inner wall, a glass pane en tering and slidable in said openings, and plates secured on opposite sides of said pane: the said plates being located outside of the light space inclosed by said frame and between said pane and the facing edges of said opening.

In testimony whereof I have aflixed my signature in presence of two witnesses.

HARRY E. CAMPBELL.
